I think this quote by Ralph Waldo Emerson speaks for itself. We are never promised tomorrow. This fact should not stress us out but encourage us to live for today and enjoy today. Procrastination is a life sucker, it keeps you thinking ahead all the time and never in the moment where you should be. If the Lord calls you to reach out to someone do it, if you need to make some changes to your life then do it and breathe easy.
